Title: Optical recording medium and optical recording method
Inventor: MOCHIZUKI HIDEAKI
IPC: G11B7/24035
Filed: 1987-12-08
Abstract: PURPOSE:To enhance the flexibility of software production and to reduce the cost at the time of small-quantity production by constituting the title medium in such a manner that a change in optical properties is maintained even for reproducing light of the wavelength which does not belong to a specific absorption band. CONSTITUTION:This optical recording medium is constituted by providing a transparent optical recording layer 2 which is transparent except in a specific absorption wavelength region on a transparent substrate 1 and providing a reflecting layer 3 thereon. The optical recording layer 2 is so constituted as to generate the change in the optical properties by absorbing the recording light belonging to the specific absorption band and to maintain the change in the optical properties even with the reproducing light of the wavelength which does not belong to the specific absorption band. Since the change in the optical properties generated at the time of recording covers nearly the entire wavelength region, the signals are detected as the discontinuity of the reflected light for the reproducing light which does not belong to the absorption wavelength region of the recording layer 2 (i.e., the recording layer is transparent to the reproducing light). The need for the process for producing a costly stamper in the manufacture of CDs is thereby eliminated and the small-quantity production of the CDs and CD-ROMs of the same software is executed at the low cost with ease.

Title: Nonoriented silicon steel sheet with low noise and low residual magnetic flux density
Inventor: NINOMIYA HIRONORI
IPC: C23C10/46
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To obtain a nonoriented silicon steel sheet capable of preventing rush current due to magnetic deviation without causing an enlargement of the size of equipment, free from the problem of noise due to magnetostriction, and reduced in residual magnetic flux density, by forming a concentration gradient of Si in a thickness direction and regulating the composition of the surface of the steel sheet so that Si concentration can be specified and magnetostriction can be decreased. SOLUTION: In this nonoriented silicon steel sheet, Si concentration in the surface layer is 5.5-7.0wt.% and the lowest Si concentration in the vicinity of the center of sheet thickness is lower by >=0.5wt.% than the Si concentration in the surface layer. A concentration gradient of Si is actively formed in order to reduce residual magnetic flux density. When the Si concentration in the surface layer is in the vicinity of 6.6wt.%, noise can be decreased. Further, it is preferable to regulate the average value of the Si concentration in the whole sheet-thickness direction to <=6.6wt.% because rush current is increased when saturation magnetic flux density is decreased. Moreover, by incorporating, by weight, 0.002-0.012% C, 0.02-0.5% Mn, and further 0.0005-0.002% B, deterioration in workability, caused by the increase of the Si concentration in the surface layer, can be prevented.
